Routing Options

With the request body parameter options, advanced routing options can be specified for a directions request.

The options parameter is a JSON object, multiple of the here mentioned parameters can be set. For structure refer to the examples.

WARNING

Some of the options below rely on auxiliary data included in the graph, see External storages

Available parameters

options.avoid_borders

String value specifying which borders to avoid. Only for driving-* profiles.

Value	Description
"all"	for no border crossing
"controlled"	cross open borders but avoid controlled ones

options.avoid_countries

An integer array of country ids to exclude from routing with driving-* profiles. Can be used together with "avoid_borders": "controlled". The list of countries and application examples can be found in the country list.

"[11,193]" would exclude Austria and Switzerland.

options.avoid_features

A string array of features to avoid. The available features are :

Feature	Available for
highways	driving-*
tollways	driving-*
ferries	driving-*, cycling-*, foot-*, wheelchair
fords	driving-*, cycling-*, foot-*
steps	cycling-*, foot-*, wheelchair

options.avoid_polygons

Comprises areas to be avoided for the route. Formatted as geojson polygon or geojson multipolygon.

options.profile_params

An object of additional routing parameters for all profiles except driving-car:

options.profile_params.weightings

Weightings will prioritize specified factors over the shortest path. The value is an object that can have the following properties:

• steepness_difficulty: Integer specifying the fitness level for cycling-* profiles. The preferred gradient increases with the value.

  Value	Fitness level
  0	Novice
  1	Moderate
  2	Amateur
  3	Pro

• green: Integer value specifying the Green factor for foot-* profiles.

  Value	Green factor
  0	normal routing
  1	prefer ways through green areas over a shorter route

• quiet: Integer value specifying the Quiet factor for foot-* profiles.

  Value	Quiet factor
  0	normal routing
  1	prefer quiet ways over a shorter route

options.profile_params.restrictions

An object specifying restrictions for cycling-*, driving-hgv or wheelchairprofiles.

• for driving-hgv:

  Parameter	Type	Description
  length	Number	Length restriction in meters.
  width	Number	Width restriction in meters.
  height	Number	Height restriction in meters.
  axleload	Number	Axle load restriction in tons.
  weight	Number	Weight restriction in tons.
  hazmat	Boolean	Specifies whether to use appropriate routing for delivering hazardous goods and avoiding water protected areas. Default is false.

• for wheelchair:

  Parameter	Type	Description
  surface_type	String	Specifies the minimum surface type. Default is "cobblestone:flattened".
  track_type	String	Specifies the minimum quality of the route. Default is "grade1".
  smoothness_type	String	Specifies the minimum smoothness of the route. Default is "good".
  maximum_sloped_kerb	Number	Specifies the maximum height of the sloped kerb in meters. Values are 0.03, 0.06(default), 0.1 or any.
  maximum_incline	Integer	Specifies the maximum incline as a percentage. 3, 6(default), 10, 15 or any.
  minimum_width	Number	Specifies the minimum width of a road in meters.

options.round-trip

An object with specifications of a round-trip:

Parameter	Type	Description
length	Number	The target length of the route in m (note that this is a preferred value, but results may be different).
points	Integer	The number of points to use on the route. Larger values create more circular routes.
seed	Integer	A seed to use for adding randomisation to the overall direction of the generated route (optional).

options.vehicle_type

For profile=driving-hgv only. It is needed for vehicle restrictions to work (see tag filtering). Possible values:

• hgv
• bus
• agricultural
• delivery
• forestry
• goods

Border restrictions

Examples for routing options object with border restrictions:

Do not cross country borders at all

{"avoid_borders":"all"}

Do not cross controlled borders (i.e. USA - Canada) but allow crossing of open borders (i.e. France - Germany)

{"avoid_borders":"controlled"}

Do not route through Austria or Switzerland

{"avoid_countries": [11,193]}

Pass open borders but do not cross into Switzerland

{"avoid_borders": "controlled","avoid_countries": [193]}
